Error: Illegal access to … when flashing custom board emmc

[Damian]

Hello,

I want to upgrade my hardware with OSD32MP157C from dunfell to new openstlinux kirkstone 4.1 release november 2022 because we want to use Linux RT.

I have written custom device tree files based on BRK (https://github.com/octavosystems/OSD32MP1-BRK-device-tree). We use EMMC.

Compiling for tf-a, u-boot, fip and kernel is fine.

However when I try to flash my image flashlayout to my custom board I get a “ERROR: Illegal access to 0xfffffff0:”

See following console output:

Board does no reconnect to host …

What is wrong in my configuration or device tree?

Error messages come from tf-a, not sure if it is related to u-boot and fip.

Is an update to openstlinux 4.1 release planned with BRK device trees? If yes, when is it planned?

Any suggestion is appreciated! Thanks!

Damian,

Apologies for the late reply. Currently Octavo’s plan is to support major revisions of OpenSTLinux. Here is the latest meta-octavo layer that supports OpenSTLinux v4.0: https://github.com/octavosystems/meta-octavo-osd32mp1/tree/kirkstone. The device tree files are added in as patches(for example: https://github.com/octavosystems/meta-octavo-osd32mp1/tree/dunfell/recipes-kernel/linux/files for the kernel).

Best,

Neeraj
